建筑伸縮縫即伸縮縫,是指為防止建筑物構件由于氣候溫度變化(熱脹、冷縮),使結構產生裂縫或破壞而沿建筑物或者構筑物施工縫方向的適當部位設置的一條構造縫。伸縮縫是將基礎以上的建筑構件如墻體、樓板、屋頂(木屋頂除外)等分成兩個獨立部分,使建筑物或構筑物沿長方向可做水平伸縮。

類型:GQF-C型、GQF-Z型、GQF-E型等其它 伸縮縫又稱溫度縫學科分類建筑學應用領域

  一 主要作用防止房屋因氣候變化而產生裂縫。其做法為:沿建筑物長度方向每隔一定距離預留縫隙,將建筑物從屋頂、墻體、樓層等地面以上構件全部斷開,建筑物基礎因其埋在地下受溫度變化影響小,不必斷開。伸縮縫的寬度一般為2厘米到3厘米,縫內填保溫材料,兩條伸縮縫的間距在建筑結構規范中有明確規定。
